No, the trial version has no restrictions whatsoever; you have access to the full potential of SimpleSYN. There is merely a dialog window on startup informing you how many days you have left on the test version, which you have to manually confirm.  You can use and test SimpleSYN for 30 days, for free and noncommittal. After the trial period has ended SimpleSYN cannot be started.

This message can be triggered by flawed Add-Ins from Third Party manufacturers. Outlook Add-Ins from Third Party manufacturers can hinder communication between SimpleSYN and Outlook.

Known problems: You may receive this message if you have the Apple Mobile Device Support Add-In installed, which is automatically installed by iTunes. The Add-in may make the PST file unusable for other applications when Outlook is shut down. Then SimpleSYN will also no longer be able to access the PST file.

To avoid the problem do not close Outlook while SimpleSYN is running.

If you are not using iTunes to synchronize an iPhone/iPod with Outlook, you could also deactivate the Add-in in Outlook.

If SimpleSYN cannot establish a connection make sure the following is correct:

  1. Make sure SimpleSYN is installed and started on both the client and the server computer
  2. At least one computer has to be configured as SimpleSYN server and a second as SimpleSYN client
  3. Install the latest version of SimpleSYN on all computers that are to be synchronized
  4. Make sure you have an active internet connection on both computers
  5. Check whether the time is correctly set on both computers. Set the same time on both computers.

Additionally: 

  1. Make sure the correct server has been selected on the SimpleSYN clients.
  2. Make sure the password has been entered correctly.

The message "destination folder was not found" appears if the top folder level in Outlook (eg "Personal folders") has been named differently on the SimpleSYN client and SimpleSYN server. In this case, SimpleSYN can not assign the destination folders automatically because no new PST files are created by SimpleSYN.

Click on the "Select a different target folder" link and select the folder where you want to sync.

Alternatively, you can name the highest folder level identically on all computers in advance.

Press on your server computer inside of SimpleSYN’s main window once the “Alt” key to open the main menu and choose the menu item “View > State Properties.

If you open the state database properties (Tab “General”) on the server, do you see any old client that is not synchronized anymore (you can see this from the last synchronization date)? 

If yes, please click on this client and click on “remove”. This will delete the status for the selected client will make some space available in the status database.

If a computer is not reachable over network or Internet, then the synchronization is carried out as soon as the computer is back in the network or online and SimpleSYN has established a connection with the SimpleSYN server.

All Outlook items that were changed or created up to that point are automatically recognized and synchronized by SimpleSYN.

SimpleSYN can not be used to synchronize between a POP3 account and an IMAP account. Use the same account type on the PCs (either POP3 or IMAP).

If you use a POP3 account on all PCs, you can also synchronize the e-mail folders (for example, Inbox) with SimpleSYN.

If you use an IMAP account on your PC, then the e-mail folders are automatically synchronized by default, since an IMAP account is server-based. The e-mail folders of an IMAP account should therefore not be selected in addition to the synchronization, since otherwise it can lead to complications with SimpleSYN (as of version 5, e-mail folders of an IMAP account are also no longer selectable). If you use an IMAP account, SimpleSYN allows you to synchronize all other local folders (such as tasks, calendars, contacts, or notes).

If you want to exit SimpleSYN if Outlook is closed, follow these steps:

  1. Right-click on the SimpleSYN icon in the Windows notification area and choose “Exit”
  2. Close any Outlook window
  3. Open the SimpleSYN Add-In configuration file with a text editor like notepad. The configuration file can be found in:

    At Version 4:
    C:\Users\[User name]\AppData\Local\SimpleSYN\4.0.0.0\[Outlook profile name].addin.config

    At Version 5:
    C:\Users\[User name]\AppData\Local\SimpleSYN\5.0.0.0\[Outlook profile name].addin.config


  4. Add the following code in the section between <appSettings> and </appSettings>:
    <!-- SimpleSYN is exited when Outlook is being closed. -->
    <add key="AutoExitSimpleSyn" value="true" />
    <!-- SimpleSYN is started if the Add-In is being loaded. -->
    <add key="AutoStartSimpleSyn" value="true" />
  5. Open Outlook again.

Category: Installation, Version 4.x

In that case, you probably have an Office 365 version from the Microsoft App Store installed.

Programs from the Microsoft App Store can not currently recognize SimpleSYN version 4 (these programs are isolated from the rest of the system). Office 365 version from the Microsoft App Store supports SimpleSYN version 5.

Please reinstall Outlook / Office at https://www.office.com/setup

Then everything should work and go through the installation.
